Primary Lesion
are lesions in the early stages of development or change. They are flat, no-palpable changes in skin-such as a macule-or by elevations formed by fluid in a cavity such as vesicles or pustules.
Macule, Papule, Wheal, Tubercle, Tumor, Vesicles, Bulla, Pustule, Urticaria, Cyst
Macule
Is a flat spot or discoloration on the skin such as a freckle. They are neither raised nor sunken.
Primary Lesion
Papule
a small elevation on the skin that contains no fluid, but may develop into a pustule.
Primary Lesion

Primary Lesion
Tumor

Nodules-are often referred to as tumors, but they are smaller bumps caused by conditions such as scar tissue, fatty deposits or infections.
Tubercle
is an abnormal rounded, solid lump larger then a papule. Lipoma, erythema, nodosum, and cysts are tubercles.

Secondary Lesion
Acne Excoriee
is a disorder where clients purposely scrape off acne lesions leaving scarring and discoloration.
Secondary Lesion
Hypertrophy
is an abnormal growth, many are benign, or harmless, However some can be dangerous or cancerous. Hypertrophic is used to describe thickening of a tissue (the opposite is atrophy, which means thinning)
Keratoma
is an acquired thickened patch of epidermis, a callus, Or if the thickening grows inward it becomes a corn.
Type of hypertrophy
Keratoses
is an abnormally thick buildup of cells. Hyperkeratosis- is a thickening of the skin caused by a mass of keratinized cells, keratinocytes. Actinic keratoses, pink or flesh colored precancerous lesions that feel sharp or rough are a result of sun damage and should be checked by a dermatologist.

white spots or areas on the skin from a lack of pigment cells, can worsen with time and sun (hypo)
skin cancer
forms when cells begin to divide rapidly and unevenly caused by damage to DNA. There are 3 types, named after the type of cells that are affected. Basal cell carcinoma, squamous cell carcinuma, and malignant melanoma.
Basal cell carcinoma
most common and least servere. Often appears as light pearly nodules. Basal cells dont spread as easily and can be easily removed.
